Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2025-09-30T18:21:27+00:00 2025-09-30T18:21:27+00:00 James Helferty (NVIDIA) jhelferty@nvidia.com 2025-09-30T18:21:27+00:00 urn:sha1:8086adc90b69f3199767c0617e2c429ce6b27f67 Enables all tests/metal/ tests that can be easily enabled. These tests were not originally designed as render tests; they are generally being enabled for pipecleaning purposes, and will not be rigorously testing the corresponding funcitonality. Where they cannot be enabled as render tests, and a metallib test wasn't already enabled, a metallib test was enabled instead (where possible). Fixes #7892 2024-05-07T15:27:27+00:00 Jay Kwak 82421531+jkwak-work@users.noreply.github.com 2024-05-07T15:27:27+00:00 urn:sha1:997f040f48b5c34e20ad6b0f512bb9d1ae6e6128 * Support Metal math functions Closes #4024 Note that Metal document says Metal doesn't support "double" type; "Metal does not support the double, long long, unsigned long long, and long double data types." According to Metal document, math functions are not defined for integer types. That leaves only two types to test: half and float. As a code clean up, __floatCast is replaced with __realCast. But I had to add a new signature that can convert from integer to float. Some of GLSL functions are moved to hlsl.meta.slang. For those functions, there isn't builtin functions for HLSL but there are for GLSL and Metal. "nextafter(T,T)" is currently not working because it requires Metal version 3.1 and we invoke metal compiler with a profile version lower than 3.1. * Changes based on review comments.
